What Are Water Filter?

Water filters are a must have appliance that removes sediment, bacteria, chlorine, lead and other impurities from water making it safe to drink and taste good addressing health and palatability concerns.

These devices serve multiple purposes in different settings. In kitchens they provide clean water for drinking and cooking and better health within the household. In bathrooms they protect hair and skin from contaminants and enhance personal care routines. In commercial spaces like offices and cafes they provide customers and employees clean water and better overall satisfaction and well being.

Choose the right water filter for your needs:

For personal use, pitcher filters are convenient and portable.

For families, under-sink filters provide continuous supply of purified water for daily use.

For the whole household, whole-house systems ensures every tap has clean and safe water.

For easy installation and instant results, faucet filters are the way to go. They attach to the tap and filters water at the point of use no need for complicated setup or space.

Each has different features and purification levels based on technology. Knowing how they work, the types of filters (including faucet filters) and what’s suitable for what purpose is key to making a decision.

Water Filter Installation

Faucet Water Filters

  • Ease of Installation: Designed for a hassle-free setup, these filters can be installed directly onto your faucet in just a few minutes.
  • Compatibility: They fit 99% of standard faucets with a universal design. Remove the aerator, select the appropriate adapter from the kit, and attach the filter. 

Shower Filters

  • Simple Attachment: Unscrew your current shower head and replace it with the filter shower head.
  • Universal Fit: These filters have a global standard 4-point interface, ensuring compatibility with nearly all shower types.

Pre-Filters

  • Foundation of Filtration: Pre-filters act as the first line of defense in your water filtration system, capturing larger particles and sediments.
  • Installation: Typically installed at the point where water enters your home, they prepare the water for further purification by other filters.

Filter Principle Classification

PP Cotton Cartridge

Also known as a melt-blown PP cartridge, it uses non-toxic and odorless polyester fiber particles. After heating and melting, spraying silk, traction, accepting the formation, and making a tubular cartridge with a small size, large filtering area, pollution-free, easy to install and replace, etc., the filtration precision is 5 microns (μm). In addition to faucet water purifiers, other water purifiers generally use PP cotton cartridges at the first stage. 

Activated Carbon Cartridge

Generally used coconut shell high-temperature firing, commonly known as coconut shell activated carbon, according to its adsorption characteristics, activated carbon is mainly used to remove the odor, color, and water purification. Activated carbon can remove some of the residual chlorine and improve the taste. Generally speaking, activated carbon is used in all types of water purifiers. The average filtration accuracy is 0.2-0.5 microns (μm).

Ceramic Cartridge

Ceramic material is mainly diatomaceous earth and white diatomaceous earth, with an average filtration precision of 0.2-0.5 micron (μm), which can remove bacteria (E. coli, Salmonella, Staphylococcus aureus, and molds and other pathogenic germs), silt, rust, red worms and various suspended particles from the water. The normal number of times the ceramic cartridge can be brushed is 10-20 times. The flux can be fully restored through simple mechanical clearing and brushing without deep membrane contamination and clogging of the pores. This can effectively prevent the re-pollution of the purified water. General faucet water purifier cartridges are ceramic + activated carbon cartridges.

Ultrafiltration Membrane Cartridge

(Ultrafiltration, UF for short) using hollow fiber filtration, a new technology with a filtration accuracy of 0.01 micron (μm), can completely filter out sediment, red worms, bacteria, rust, colloids, and other harmful substances in the water and retain the original trace elements and minerals in the water. The ultrafiltration membrane cannot remove residual chlorine and improve taste. 

RO Membrane Cartridge

(Reverse Osmosis, referred to as RO) filtration precision is 0.0001 micron (μm). It can thoroughly filter out inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, and other impurities in the water, filtering only water molecules of pure water.

Knowledge of Water Filter

TDS

Total Dissolved Solids (TDS) encompass the collective presence of both organic and inorganic substances, such as minerals, salts, metals, and ions, dispersed in a specific volume of water.

The following list details common total dissolved solids that may be present in your water.

pH

The pH scale measures the acidity or alkalinity of a solution based on its hydrogen ion concentration. Ranging from 0 to 14, a pH of 7 is considered neutral, values below 7 are acidic, and those above 7 are alkaline. Pure water, in its intrinsic state and at room temperature, has a pH of 7, making it neutral. This neutrality arises from water’s unique molecular structure. Each water molecule can dissociate into a hydrogen ion (H+) and a hydroxide ion (OH-). In pure water, the concentrations of these ions are equal, resulting in a balanced, neutral pH.

Water Filter Test

Water filtration involves various complex processes to ensure every drop of water is pure and safe.

To help you gain insight into these processes, we’ve outlined some of the most common and essential tests conducted in the field. These tests are crucial for assessing water filter performance, from chemical purity to mechanical resilience. Below, we delve into the specifics of each test, providing a glimpse into the rigorous standards that govern the water filtration industry. 

Water Hammer Test

The Water Hammer Test is conducted to assess the structural resilience of water filters against sudden and extreme fluctuations in water pressure. 

This simulation of ‘water hammer’ conditions is crucial for verifying that the filters can withstand these abrupt changes without any loss of functionality or compromise in their structural integrity.  

Physicochemical Testing

This testing method analyzes water quality parameters such as turbidity, residual chlorine, pH levels, and other chemical contaminants.

The purpose is to ensure that the water filter effectively removes or reduces these substances, thus providing safe and clean water. It is vital to confirm that the filters meet stringent water quality standards. 

Salt Spray Test

The Salt Spray Test is designed to evaluate the corrosion resistance of water filters. It exposes the filters to a highly saline environment, simulating saltwater exposure conditions. 

The primary goal is to ascertain that the filters maintain their integrity and do not corrode when exposed to such environments, ensuring longevity and durability in various operational conditions.

Mechanical Reliability Test

The Mechanical Reliability Test is essential for ensuring our water filters’ endurance and operational stability under mechanical stress and usage.

This test involves subjecting the filters to various physical forces and conditions they might encounter during regular operation. The objective is to confirm that the filters maintain performance, remain free from physical defects, and operate reliably over their intended lifespan, even under repeated or prolonged mechanical stress.
